Tracking the use of /dev/mem to toggle pins.

Details: http://chiragnagpal.com/examples.html

Not sure if this library is the appropriate home for this?

@taqtiqa-mark Just seeing this now, this crate is explicitly for interacting with PWM via the kernel sysfs interface which is portable. /dev/mem is highly architecture specific and, by its nature, requires that the userspace process performing the action have very escalated privileges.
